Description

Technical Field

[0001] This utility model relates to a labeling device, specifically a labeling device for a hot melt adhesive labeling machine, and belongs to the technical field of hot melt adhesive labeling machines. Background Technology

[0002] The working principle of a hot melt adhesive labeling machine is to heat and melt solid hot melt adhesive, then apply the molten hot melt adhesive to the back of the label, and finally use a mechanical device to stick the label onto the product. Hot melt adhesive labeling machines offer high-speed, high-precision, and high-quality labeling results, significantly improving labeling efficiency and quality.

[0003] A search revealed a labeling device for a linear hot melt adhesive labeling machine, disclosed in Chinese Patent Publication No. CN213110078U. The device includes a base and a housing located on top of the base and bolted to it. This invention, through the arrangement of a connecting shaft, a motor, a drive wheel, a driven wheel, a fixed plate, and a limiting plate, offers advantages such as rapid labeling of bottles, prevention of label detachment, ease of label replacement, and increased machine efficiency. It solves the problems of current hot melt adhesive labeling machines having limited functionality, high operational difficulty for workers, inconvenience in label replacement, and poor machine stability, which can easily cause label misalignment.

[0004] While the above solutions can quickly label bottles, prevent labels from falling off, and facilitate label replacement, the labeling devices in the aforementioned patents have difficulty positioning the bottles. When the bottles are transported by the conveyor belt, they inevitably shift slightly from their original positions, thus increasing the probability of labeling defects. To address this issue, we provide a labeling device for a hot melt adhesive labeling machine. Utility Model Content

[0005] The purpose of this invention is to provide a labeling device for a hot melt adhesive labeling machine to solve the above-mentioned problems, thereby addressing the difficulty in positioning bottles in the prior art.

[0006] This utility model is achieved through the following technical solution: a labeling device for a hot melt adhesive labeling machine, comprising a hot melt adhesive labeling machine body, a conveyor belt structure, and an installation frame. A mounting platform is fixedly connected to the bottom of the installation frame, a DC motor is fixedly connected to the upper surface of the mounting platform, a linkage swing plate is fixedly connected to the output shaft of the DC motor, a force application transition plate is rotatably connected to one end of the linkage swing plate, a linkage plate is rotatably connected to one end of the force application transition plate, an adjustment shell is fixedly connected to one side of the linkage plate, a positioning slider is slidably connected to the inner wall of the adjustment shell, and a rubber push rod is rotatably connected to one side of the positioning slider. The tight fit between the components can effectively position the bottle.

[0007] Preferably, there are four adjustment housings in total, and each of the four adjustment housings has a through hole. The design of the through hole is beneficial for the subsequent reinforcement of the positioning slider.

[0008] Preferably, a positioning bolt is inserted into the through hole of the adjusting housing, and the outer circumferential surface of the positioning bolt is threadedly connected to the positioning slider. The positioning slider can exert a positioning effect on the rubber push rod, ensuring that the rubber push rod can rotate in place.

[0009] Preferably, there are two linkage plates, and each linkage plate is fixedly connected to a control slider, which can ensure the stability of the linkage plate.

[0010] Preferably, the control slider is slidably connected to the outer wall of the dovetail slide, and the dovetail slide is fixedly connected to the bottom of the mounting frame. The dovetail slide ensures that the control slider moves stably.

Detailed Implementation

[0022] This utility model provides a labeling device for a hot melt adhesive labeling machine.

[0023] Please see Figure 1 The device includes a hot melt adhesive labeling machine body 1, a conveyor belt structure 2, and an installation frame 3. The hot melt adhesive labeling machine body 1 and the conveyor belt structure 2 are both existing publicly available technologies, and this application will not elaborate further on the hot melt adhesive labeling machine body 1 and the conveyor belt structure 2.

[0024] Please see Figure 1 The conveyor belt structure 2 is fixedly connected to the upper surface of the main body base 16. The hot melt adhesive labeling machine body 1 is fixedly connected to the upper surface of the main body base 16. The purpose of setting the main body base 16 is to ensure the stability of the conveyor belt structure 2 and the hot melt adhesive labeling machine body 1, which is beneficial to the subsequent labeling operation.

[0025] Please see Figure 1 and Figure 2 The mounting frame 3 is fixedly connected to the conveyor belt structure 2 via support plates 15. The purpose of setting up support plates 15 is to place the mounting frame 3 directly above the conveyor belt structure 2, which is beneficial for subsequent bottle positioning. There are two support plates 15 in total. The design of two support plates 15 ensures the stability of the mounting frame 3.

[0026] Please see Figure 2 and Figure 3 The bottom of the mounting frame 3 is fixedly connected to the mounting platform 4, and the upper surface of the mounting platform 4 is fixedly connected to the DC motor 5. The output shaft of the DC motor 5 is fixedly connected to the linkage swing plate 6. The purpose of setting the DC motor 5 is to effectively provide sufficient power support for the rotation of the linkage swing plate 6. The DC motor 5 is existing publicly available technology, and this application will not elaborate further on the DC motor 5.

[0027] Please see Figure 3 and Figure 4One end of the linkage swing plate 6 is rotatably connected to the force application transition plate 7, and one end of the force application transition plate 7 is rotatably connected to the linkage plate 8. The cooperation between the linkage swing plate 6, the force application transition plate 7 and the linkage plate 8 is such that when the linkage plate 8 remains stable, the rotation of the linkage swing plate 6 can effectively drive the linkage plate 8 to translate through the force application transition plate 7.

[0028] Please see Figure 3 and Figure 4 There are two linkage plates 8, and each linkage plate 8 is fixedly connected to a control slider 13. The linkage plate 8 and the control slider 13 are directly connected and maintain the linkage effect. The control slider 13 is slidably connected to the outer wall of the dovetail slide 14. The dovetail slide 14 is fixedly connected to the bottom of the mounting frame 3. The purpose of setting the dovetail slide 14 is to effectively apply the control effect to the control slider 13, ensure the smooth displacement of the control slider 13, and thus ensure the stability of the linkage plate 8.

[0029] Please see Figure 4 An adjustment housing 9 is fixedly connected to one side of the linkage plate 8. The linkage plate 8 and the adjustment housing 9 are in a direct connection state, and the two maintain the linkage effect. A positioning bolt 12 is inserted into the through hole of the adjustment housing 9. The outer circumferential surface of the positioning bolt 12 is threadedly connected to the positioning slider 10. The purpose of setting the positioning bolt 12 is to effectively ensure the stability of the positioning slider 10, so that the positioning slider 10 will not move randomly within the adjustment housing 9.

[0030] Please see Figure 3 There are four adjusting housings 9 in total, and each of the four adjusting housings 9 has a through hole, which facilitates the use of the positioning bolt 12. The inner wall of the adjusting housing 9 is slidably connected to the positioning slider 10, and the adjusting housing 9 can apply a position control effect to the positioning slider 10 to ensure that the positioning slider 10 can slide within the adjusting housing 9. One side of the positioning slider 10 is rotatably connected to a rubber push rod 11, and there are four rubber push rods 11 in total. The setting of the rubber push rods 11 can effectively push the bottle to move and achieve the purpose of positioning the bottle. Bottle positioning requires the use of an external sensor, and the sensor is a known technology, so this application will not describe the sensor in detail.

[0031] Working principle: During use, the bottle is transported on the conveyor belt structure 2. When the bottle is about to enter the hot melt adhesive labeling machine body 1 for labeling, the external sensor will sense it and start the DC motor 5 to work, driving the linkage swing plate 6 to rotate. At this time, the linkage plate 8, which is combined with the force transition plate 7, will be restricted by the dovetail slide 14 through the control slider 13. Therefore, the linkage swing plate 6 can drive the linkage plate 8 and the control slider 13 and other components to move synchronously through the force transition plate 7, thereby changing the position of the rubber push rod 11. Through the design of four rubber push rods 11, the bottle can be pushed between the four rubber push rods 11, thereby achieving the effect of positioning the bottle. According to the actual application scenario, the positioning slider 10 can be pushed manually to slide in the adjusting shell 9, and then the positioning slider 10 can be reinforced by the positioning bolt 12 to change the initial position of the rubber push rod 11. It can be used for bottles of different diameters. After positioning is completed, the bottle enters the hot melt adhesive labeling machine body 1 to complete the labeling operation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
